چکیده
The title compound, [HP(CH3)3][IrCl4{(H3C)3P}2], consists of a tri-methyl-phospho-nium cation and a tetra-chlorido-bis-(tri-methyl-phosphane)iridate(III) anion. The anion has an octa-hedral arrangement of ligands, with the tri-methyl-phosphane groups occupying trans positions. The Ir(III) atom sits on an inversion center with one P(CH3)3 ligand and two chloride ligands in the asymmetric unit. The tri-methyl-phospho-nium cation is disordered about a twofold rotation axis. The title compound is the first structurally characterized tetra-chlorido-bis-(phosphane)iridate complex.

The crystal structures of two solvates of fac-tri-chlorido-tris-(tri-methyl-phosphane-κP)rhodium(III) are reported, i.e. one with water in the crystal lattice, fac-[RhCl3(Me3P)3]·H2O, and one with methanol in the crystal lattice, fac-[RhCl3(Me3P)3]·0.5CH3OH. These rhodium compounds exhibit distorted octahedral coordination spheres at the metal and are isotypic with the analogous iridium compoun...

The title complex, [Ir(C5H8NO2)H(C3H9P)3]PF6, has two independent anion-cation pairs in the asymmetric unit. The geometry about each Ir(III) atom is pseudo-octa-hedral with a meridional arrangement of the P(CH3)3 ligands, N,O-bidentate coordination of prolinate and a hydride ligand trans to the prolinate N atom. The independent Ir(III) moieties are joined by N-H⋯O hydrogen bonds and the N-H⋯O b...

The title compound, [Ir(C5H10NO2)H(C3H9P)3]PF6·0.675CH2Cl2, an iridium compound with a meridional arrangement of PMe3 groups, O,N-bidentate coordination of d-valine and with a hydride ligand trans to the N atom is compared with the l-valine complex reported previously. As expected, the complexes from the corresponding l and d isomers of valine crystallize in enanti-omorphic space groups (P43 an...

The title compound, [Ir2H2O(C3H9P)6](BF4)2·2H2O, was isolated from the reaction between [Ir(COD)(PMe3)3]BF4 and H2 in water (COD is cyclo-octa-1,5-diene). The asymmetric unit consists of one Ir(III) atom bonded to three PMe3 groups, one hydride ligand and half an oxide ligand, in addition to a BF4 (-) counter-ion and one water molecule of hydration. The single oxide ligand bridging two Ir(III) ...
